This may depend on your router (and the specific firmware you may be running), but I've found that my Xbox behaves best when it is allowed to be assigned an address from the DHCP server in the router rather than giving it a static address during setup. On the router, then, you'd need to take the MAC address for the Xbox and have the router correspondingly assign a static IP address so it remains the same whenever the Xbox is restarted. Forward ports as usual for online play.

i'm pretty sure it has a static IP address, so that's not an issue. i just tried to connect to him though, and despite the fact that we both have Open NAT types, we STILL can't connect to each other. what the hell is going on here?
